rection, as well as to move in a circumferential direction to a limited extent.

Secured to the inner face of the telly and extending inward therefrom is a circular series of plunger-s 8. Each plunger comprises an outer tubular member 9, the outer end of which is preferably split, as shown at 10, to form two spring arms 11, the outer ends of which are bent in opposite directions, to form attaching portions 12 which are secured'to the inner face of the telly in any convenient manner, vice shown in the drawings consisting of a hoop or-band l3, embracing all of the attaching portions of the plungers and embracing the telly. Each plunger further embodies an inner section 14 which is of a To (172 whom it may-concern: M lie it known that I, JOHN-GIBSON, a citizen of the United States, residing at Courin the county oii'stutsman an State of North Dakota, have invented new and Spr ng Vehicle- Whecls, of which the following is a specitication.

This invention relates to spring veh cle wheels, the object in view being to provide a wheel which will take the place of the usual pneumatically tired wheel, and absorb the vibrations, without any liability of transmitting the same to axles and body of lVith the above and other objects in view,

the invention consists in the construction,

the outer section, and said inner section has its inner extremity held between the circumferential flanges of the hub, as shown, and is pivotally connected with said flanges by means of a pin 15, thereby allowing a sufficient pivotal movement of each plunger, to admit of the yielding of the telly in both a radial or circumferential direction.

Disposed around the inner section of each plunger is a coiled spring 16, the-inner end of which is seated will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed outin the claims hereunto apended.

In the drawings: Figure lis a side elevation of a spring wheel, embodying the present invention. Fig. 2 is a longitudinal section through a portion thereof. Fig. 3 1s a cross section through half of the wheel. Fig. 4 is a detail view of one of the plungers and the parts immediately connected therewith. Z

The wheel contemplated in this invention comprises essentially a hub 1, and a telly 2, the same being connected together for relative movement,"in a manner hereinafter described. I

The hub is preferably provided with side plates 3 secure to the inner and outer faces thereof, and extended at their periphagainst a shoulder 17 on outer end of the spring bears againstthe inner end of the outer tubular section of the plunger, so that the tension of said spring is always exerted to hold the outer section of the plunger outward with a yielding pressure. At this point, it willzbe noted that each plunger has an outward and inward sliding movement between the annular 1 b d th Outer f f th h b, so bands, and is also adapted to move 1n the as to form projecting circumferential direction of length or circumterence of said flanges 4.

As a result, all vibration-and jar is absorbed by the wheel and prevented from being transmitted to the axle or body of the vehicle, in connection with which the wheel is used. The spring arms of the outer tubular section of each plunger also serve to absorb vibration, and furthermore to allow of the slight pivotal movement between the inner member of the plunger and the wheel hub.

What is claimed is:

1. A spring vehicle wheel, comprising a hub, a telly, annular bands of equal size intermediate the hub and telly and formed with circumferential slots, spokes connect ing the hub and bands, plungers connected to the telly and extending inward between the annular bands and between the spokes, cushioning springs yieldingly sustaining plungers, circumferentially acting cushienspokes, and cushioning springs yieldingly 1 sustaining said plungers, the outer ends of the plungers embodying integral spring attaching portions which are slidingly-.connected with the telly.

3'.- A spring vehicle wheel, comprising a hub, a telly, annular bands of equal size in termediate the hub and felly, spokes connecting the hub and bands, plungers embodying outer tubular sections attached to the telly, inner sections slidable in the outer sections and having a jointed connection with the hub, and springs coiled around the inner spoke sections and serving to press the outer spoke sections in an outward direction.
